Original application filed July 26, 1921, Serial No. {187,633. Divided and this application filed February 21, 1922. Serial No. 538,328.

To all u izcm. z'z may concern.

Be it known that I, Isrnon KITsEE, citizen of the United States, residing at Philadelq phia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Polychromat-ic Screens Integral with Moving-Picture Films, of whichthe following is a specification.

My invention relates to an improvement in polychromatic screens integral with moving picture films.

This application is a division of application filed Q uly 26, 1921. SerialNo. 487,633.

' The accompanying drawing illustrates a device with the aid of which I have pr0- duced integral polychromatic screens on moving picture films of different lengths. Some of the films were perforated, before the production of the integral screen and on some of the films I produced integral Screens without perforating the film.

In this drawing Fig. 1 is a top plan view of the device, with part of the film inserted therein. Fig. 2 is a transverse vertical section taken on line 22 of Fig. 1. Fig. 3 is a vertical longitudinal section taken on line 33 of Fig. 1. Fig. 4 is a vertical section taken on line 4- 4 of Fig. 1. Fig. 5 is a fragmentary plan view of partof the film..

In these drawings, 1 is the support or base on which the device used by me is mounted. 2 is the race-plate adapted to guide the film during the passage, so that the same may not deviate to right or left. This race-plate is held in position by the blocks 33 secured with the aid of the screws 4-4 to the support. 5 is the pressure plate, performing the oifice of keeping the film when passing through the race-plate in the desired flat-' tened position. This pressure plate is secured to the race plate with the aid of the adjustable screws 6-6 in conjunction with the springs 7-7 to produce an exact adjustment of the pressure required. The support 1 is either fastened to a working bench directly or isprovided, as shown in the drawing with legs 8-8. 9 is an angle plate secured to the base 1 and provided with a cutout part or machine slide 10. In this machine slide is positioned the carrier 11, supporting and carrying the cutter or knife 12.

This cutter or knife is shown here as comprising four serles of cuttlng knives 13, 13, 13, 13. Each series consists of a number of width. substantially equal to the width of a film from perforation to perforation. The width of each of the knives of each series corresponds to the width of the line it is desued to produce on the film. In some of the as an entirety for raising and lowering the carrier 11 and therefore the cutter 12. These adjustable means comprise here the micrometer screw 15. the means 16, here shown as a conventional knob, to mapiulate the screw, the dial 1? provided with the gradations l8 and the zero mark 19, having its counter part on the stationary block 20.

In thedrawing is also shown the film 21 in the process of being wound from the spool 22, carried through the race plate and in operative relation to one of the series of knives 13 and the means to draw the same through the race plate and in cutting contact with the different knife edges. This means 23 is here shown as a fragment of a pulley supposedly centered in a revolvable shaft and rotatedpreferab1y with theaid of an electric motor. In practice, the speed of the pulley should be comparatively great and as I have found it advisable to use a pulley of rather comparatively large diameter, I employed intermediate means to obtain the required speed of this pulley.

I Fig. 5, 21 is part. of a film as an entirety and of this film 24 represent the cutout parts and 25 the parts not cutout. These uncut parts are provided, as will hereinafter be more clearly explained with the tinted surface 26 and the coating 27.

It has to be stated that the pressure plate 5 is provided with an aperture 28, so as to allow the edges of the stationary cutter to come in operative relation with the film pro er.

he mode of operation in reducing the integral screen is substantially'as follows: I take it for granted that the film on which the screen is to be produced is about 200 feet in length (as most of the films come in lengths of 200 or 400 feet) I also take t for granted that one surface of the film is, as usual, coated with gelatine. The first step 15 to tint the uncoated surface with the reknife edges and the whole series is of a quired'color, dissolved in a medium adapted to attack the celluloid of the film. In producing the film, I make use of a dye dissolved in alcohol and add thereto an equal quantity of ether. I carried this film through the dye-bath with the aid of a revolving drum and after the film has been passed through the dye-bath and has been dried,the tinted surface is covered with a temporary "protective layer, such as gelatine, and after drying it is wound around a spool, such as is shown in the drawing at 22.

The film is then threaded through the race plate of the device. All parts, pressure plate, the cutter and such other parts as are necessary are properly adjusted, so that when the film is drawn'through the race plate the different knives of the cutter will quantity of. ther.

' cut into the film in a manner, so as to remove .the protective coating and the tinted part slightly higher than normal temperature.

screens upon cinematographic film, which method consists in tinting oneof the sur- Having now described my invention, what I claim as new and desire to secure by Letters Patent is: 1

1. The method' of producing integral faces of the film, then coating said tinted Surface with a protective coating, and then with the aid of stationary cutters removing said protective coating and the underlying tinted'surface of the film along unbroken longitudinal lines.

2. The method of producing integral screens upon cinematographic film, which method consists in tinting one of the surfaces of the film, then coating said tinted surface with a protective coating, then with the aid of stationary cutters removing said protec tive coating and the underlying tinted surface of the film along unbroken longitudinal lines, then tinting the cleared lines with a tint different from the first tint, and then removing the remaining protecting coating.

3. The method of producing integral screens upon cinematographic film, which method consists in causing on a previously tinted film, the surface thereof protectively coated, to be produced in one and the same operation a series of longitudinal and unbroken clear lines with the-aid of stationary cutting edges, causing then the so produced clear lines to be tinted in a color different from the first tint, whereby longitudinal unbroken lines ofone tint are produced, interspaced by longitudinal unbroken lines of a different tint.

4. In the art of producing integral screens upon cinematographic film, the step which consists in causing with the aid of a series of stationary cutting edges, a series of clear unbroken lines to be produced on a formerly tinted film interspaed by unbroken lines of the former tint.

In testimony whereof I aflix my ISIDOR I ITSEE.
